The project manager is facing a rush project and the PMO office has authorized the project team to work 7.0 days per week (work week for this project). The PM would like to provide the PMO office with a project duration estimate based on a 75% probability of completion on time. The project has an estimated duration of 67 work days, which was based on estimates including an optimistic estimate of 36 and a pessimistic estimate of 82. The PM has looked up 75% on her probability table for a normal distribution and Z is equal to 0.67. How many work weeks should the PM tell the steering committee the project will take?
